RAZOR WITH STATIONARY BLADE ANY) MOVABLE SHEAR PLATE Filed Jan. 50, 19560? INVENTOR. Eff V0.4? M157} BY 7 [a v H/ flame United States PatentO1,839,829 iiAZoR WITH STATIONARY BLADE AND MOVABLE SHEAR PLATE Thisinvention relates to dry shavers and more par ticularly to anon-electric dry shaver.

It is an object of the present invention to provide av non-electric dryshaver which may be carried in ones pocket and which will shave the userwithout requiring electricity or soap and water or shaving lather.

It is another object of the present invention to provide a non-electricdry shaver which includes a grooved channel member which receivestherewithin from either end an inner cutter which cooperates with aslotted cylinder rotatably mounted on the outside of said channelmember, the stationary inner cutter cooperating with the rotating outer"cutter to provide a cleaner, closer and quicker shave without requiringelectricity or lather.

It is still another objectof the present invention to provide anon-electric dry shaver of the above type wherein the inner cutter maybe replaced from either end of the channel member and the cuttercylinder without disassembling any parts of the shaver.

It is.still another object of the present invention to provide anon-electric dry shaver of the above type which includes an inner cutterhaving oppositely disposed blades which cooperate wtih the rotatingouter cylinder to shave both on the 'up and down strokes, to provide ashave in one-half the time; in other words, to provide a nonelectric dryshaver which shaves when moved in either direction.

1 It is still another object of the present invention to provide .anon-electric dry shaver of the above type wherein the inner cutterblades cooperate with the inside surface of the slotted outer cylinderduring rotational movement of the latter toprovide a self-honing actionwherebythe blade edges are, retained sharp and true over relatively longpe ds Q tim 1" It is still another object of the present invention toprovide a non-electric dry shaver of the above type wherein the innercuttenrnay be removed as a unit from either end of the channel andslotted cylinder to be replaced when worn by a new inner cutter unitwithout the necessity of handling the cutting edges of the inner cutterblades at any time and to prevent accidents thereby.

For other objects and for a better understanding of the invention,reference may be had to the following detailed description taken inconnection with the accompanying drawing, in which: I

' particularly to Figs.

Patented June 24, 1958 Fig. 6 is a view similar 'to Fig. 5 of a modifiedform of the present invention.

Referring now more in detail to the drawingandmore v1 through-5, 10represents a handle having a, semi-circular side and bottom edge 11 anda flat straight upper edge 12, substantially as illustrated. The handle10 may be formed of plastic, metal or other suitable materialand ispreferably hollow to reduce the weight thereof. V I

A-pair of angle brackets 13 are mounted at opposite ends of the upperhorizontal edge 12 by means of the countersunk screws --14 or othersuitable fastening means. A grooved channel member -15 having asegmental cylindrical'outer surface is fixedly mounted between theangle-brackets 13 by means of the internally threaded openings 16provided at the ends thereof and the countersunk screws 17 positionedtherein, the screws 17 passing through'the' openings provided in theangle brackets 13.

The upper portion of the channel member 15 is. cut away (Fig. 3) toreveal a rectangular inner opening 18 which communicates at itsupper'edges with the grooves or tracks 19gprovidedalong the oppositesides interiorally of the channel member15.

An inner cutterindicated generally at 20 (Fig. 4) is slidably'positioned within the grooves 19. The ends of the top wall 21 and sidewalls-22 are connected by the integrally formed, trapezoidal shaped endportions 23, The lower edges of 1 the side -walls ,22 are integrallyformed with the outwardly andupwardly bent clamping (Fig. 5) whichvportions 24 of U-shaped cross section resiliently position therewithinagainst the side walls22 the oppositely disposed inner cutter blades25having the, cutting edges 26 disposed uppermost and in complemen taryrelationship to e'achothen An outer cutter is provided and comprises -aslotted cylinder 27 rotatably mounted on the channel member anglebrackets 13; The slotted cylinder 27 includes the thickened end portions28 which are adapted to abut the flanges 13 to prevent longitudinaldisplacement of the slotted cylinder ofif of the channel member 15, aswill be obvious,.the .sl'ottedcylinder 27. and end portions 28 thereofbeing freely spaced from the supporting surface 12 of the handle 10tofacilitate the rotational movement thereof when moved across the skinof the shaver. The cylinder 27 is providedwith the slots 29. extendingover substantially the entire surface thereof, the slots 29 being.arranged in longitudinally Ispacedsections, substantially asillustrated. As shown in Fig. 5, the cutting edges- 26 are in contactwith the inne'r'surface of the slotted cylinder27 and cooperate withltherotating,cut-, ting edges .of the slots 29. tocutand, shear, the beardas the cylinder 27 is' moved back and forth across the skin of theshaver. Due to the angle with the vertical and the complementaryposition of the inner cutting blades 25, it'will be noted that the beardwill be cut in both directions of the outer cylinder 27 on both the upstroke and down stroke, to effect an economy of time during the shavingoperation. It will also be noted that the continuous contact between thecutting edges 26 of the inner cutter and the inner surface of theslotted cylinder 27 provides an automatic honing action to retain thecutting edges 26 sharp and true for long periods of time.

After the blades 25 have become worn, the inner cutter 20 may be ejectedoutwardly through either end of the channel 15 and slotted cylinder 27(Fig. 1) and a new inner cutter 20 inserted (Fig. 2). The new cutter maybe pushed inwardly into the grooves 19 to automatically eject the oldinner cutter. Thus, the inner cutter blades 25 may be replaced in aneasy and ready mannerthrough either end of the device without thenecessity of at any time having the users fingers come 15 intermediatethe into contact with the cutting edges 26 and to prevent cuts thereby.During the shaving operation, the beard hairs will be passed inwardlythrough the slots 27 and moved against the stationary cutting edges 26to cut the same with a shearing action to provide a quicker, closershave, without the requirement of either electricity or shaving lather.may be used on camping trips and in isolated areas without requiringeither a source of poweror shaving lather.

The slots 29 are symmetrically arranged and'of similar shape and maybeof any suitable geometric configuration for example, they may bestraight, circulan-diagonal, elliptical, oval, polygonal or rhombic. Thedistance between the cutting edges 26 is approximately one-quarter of aninch.

'It will be noted that the provision of the oppositely disposed blades25 permits cutting on both the up and down stroke to not only effect aneconomy of time during shaving but to eliminate the necessity of markingthe handle 10.

Referring now particularly to Fig. 6, there is shown a modified form ofthe present invention wherein the inner cutter a is provided with a pairof parallel. blades 25. Theinner cutter 20a includes a rectangular topwall 21a integrally formed along the oppositely longitudinal edgesthereof with the parallel inclined side walls'22a against the outersurfaces of which the blades are positioned. The ends of the top wall21a and side walls 22a are connected by parallelogram-shaped endportions, not shown. The lower edges of the side walls 22a areintegrally formed with the outwardly and upwardly bent clamps 24a ofU-shaped cross section which resiliently retain therewithin the blades25, the upper edges of the clamps 24a extending upwardly above the topwall 21a. In this form of the invention, the device will shave on onlymovement of the slotted cylinder in one direction, However, the twoblades will cooperate to reduce the shaving time, as will be obvious.

In other respects, the form of the invention shown in Fig. 6 is the sameas that shown in Figs. 1 through 5, and like reference numerals identifylike parts throughout the several views.

While various changes may be made in the detail construction, it shallbe understood that such changes shall be within the spirit and scope ofthe present invention as defined by the appended claims.

The top walls 21 and 21a are provided with perforations and30a'respectively to permit the passage of cut hair downwardlytherethrough.

The holder 24 may, of course, be used with only one blade 25 withoutdeparting from the scope of the invention as will be obvious.
